Improving input

• The input() function can generate two exceptions: EOFError or KeyboardInterrupt on end-of-file(EOF) or canceled input.
• Create a wrapper function, perhaps safe_input() that returns None rather rather than raising these exceptions, when the user enters ^C for Keyboard Interrupt, or ^D (^Z on Windows) for End Of File.
• Update your mailroom program to use exceptions (and IBAFP) to handle malformed numeric input
